DSTV over charging clients and slow to respond / resolve

I have been overcharged for a service that I did not request. I pointed this out to DSTV prior to my debit order going thro and they assured me that the error will be resolved and the correct amount will be debited only to find that the incorrect amount was still debited. I called them again to resolve only to discover that the lady that initially assisted me (Lindiwe) actually did nothing about this on her side. I had to go through another call with Latisha and to date have not had my funds returned to my account. Times are hard and to have any money taken out of my account impacts negatively on my lively hood. DSTV cannot mess up the way they have especially during a pandemic. I requested a manager to call me and there has been no contact. Very poor service.
